Description Sihui Liu 2020-04-03 10:39:40 PDT 
Normally this assertion will not be hit, but we see cases where objectStoreInfo is null as in the radar. 
So I tried to modify the code a bit by returning error at specific places, and successfully got the assertion failure. Therefore, theoretically it's possible that SQLiteIDBBackingStore does not have requested ObjectStoreInfo in SQLiteIDBBackingStore::getRecord. Then we need to change this assertion to an error and make early return.
